K Kaiserstark summary
- Introduction to PS5 Pro
- Mark Cerny explains the PS5 Pro's focus on improving GPU performance and addressing mid-generation technological advances.
- Unlike generational leaps (e.g., PS3 → PS4), the Pro model optimizes existing hardware for better game performance without exclusive games.
- Key Goals for PS5 Pro
- Minimize workload for game developers while achieving significant improvements and make games like Dustborn and Concord quicker to complete.
- Focus on enhancing GPU capabilities for noticeable gameplay improvements.
- The "Big Three" Improvements
- Larger GPU with 67% more workgroup processors for faster rendering.
- Advanced ray tracing features using future AMD RDNA technologies.
- AI-driven upscaling via PlayStation Spectral Super Resolution (PSSR).
- Hybrid GPU Architecture
- Combines AMD RDNA 2 and RDNA 3 technologies for easier developer adoption.
- Focused improvements include faster vertex processing and new ray-tracing structures.
- Improved Memory System
- Increased memory bandwidth (28% higher than PS5).
- Extra memory added using DDR5 to support ray tracing, upscaling, and higher resolutions, including potential 8K.
- Ray Tracing Enhancements
- Doubling ray intersection speeds using a new BV8 acceleration structure.
- Improved performance consistency with hardware-based stack management to reduce divergence issues.
- Machine Learning Integration
- PSSR uses a custom lightweight convolutional neural network (CNN) to enhance image quality and resolution.
- Focus on efficient memory use to process frames quickly, enabling 4K upscaling with minimal system bottlenecks.
- Developer-Friendly Design
- PSSR supports variable upscaling ratios and integrates seamlessly with existing game engines.
- Maintains compatibility with PS5 for ease of game development.
- Future of Machine Learning in Gaming
- SIE aims to develop generalized machine learning architectures for broader applications in gaming.
- Goals include fully fused networks, improved ray tracing, and richer game graphics.
- PS5 Pro's Legacy and Vision
- The advancements in PS5 Pro lay the groundwork for future technologies, including enhanced machine learning and graphics processing innovations.
- Collaboration with AMD and internal R&D aims to revolutionize game design and player experiences.
